Abstract:
The excessive application of in soil conditioner on paddy rice not only increase the production
but also give a significant effect on land degradation, environmental problems and the increasing
of rice yield losses. The experiments had been conducted to investigate the effect of biofertilizer
(consortia of phosphate-solubilising mircrobes and nitrogen-fixing bacteria) and soil conditioners
(straw compost and charcoal husk) to increase growth and yield of paddyrice. The experiment
was arranged as randomized block design (RBD) with three replications. The combination
treatments consisted of biofertilizers(phosphate-solubilizing microbes (Pseudomonas mallei.
P.cepacea, Penicilliumsp. and Aspergillussp, and nitrogen-fixing bacteria (Azotobactersp. and
Azosprilillumsp.), which were ; without bio fertilizer; 5 L ha-1 of liquid bio fertilizer; and 50 kg
ha-1 of solid biofertilizer. While the soil conditioners ,which were : without soil conditioner;
straw compost; charcoal husk; and cow manure. The results of experiment revealed
thatbiofertilizer and soil conditioners increased growth and yield of paddy rice. |
